Ch9 warm up

In a cave on a new planet that the star gate has discovered. Jonna, Marc and Cal are on their first mission without the main crew. Jonna wants to venture further into the caves and find out where the light is coming from but Cal wants to find a way out. Marc is trying to keep them from fighting and direct their attention to the fact that each cave entrance they go through they keep getting more lost. All of a sudden they reach where the light is and find a vast city but no one there. It is as if the city is buzzing with invisible people.
